Multiple myeloma is a frequent hematologic malignancy, in which the International Stratification Score (ISS) is widely used to estimate the overall survival. However, there are no studies in Latin America evaluating its performance. This study aims to describe the ISS performance in the overall survival estimation for newly diagnosed multiple myeloma patients in Uruguay.
This is a retrospective registry-based survival analysis through the Grupo Uruguayo de Mieloma Múltiple (GUMMA) database, including newly diagnosed multiple myeloma patients from January 2001 until May 2019.
249 patients were included, 51.81% males and an average age of 63.49 years. According to ISS and Durie-Salmon score (DSS), 47.79% and 82.3% were ISS III and DSS III, respectively. Also, 32.3% were DSS B. Auto hematopoietic stem cell transplantation was performed in 31.73% of patients, and bortezomib was used in 44.18% as frontline therapy. The overall survival was 80% for ISS1, 64.9% ISS2, and 48.6% ISS3 (Log-Rank; p &lt;0.01). The average overall survival was 116.5 months for ISS 1, 77.6 months for ISS 2, and 57.8 months for ISS 3. The hazard ratio between ISS II and ISS I was 2.42 (95% CI 1.10-5.33; p&lt;0.05), and 3.94 (95% CI 1.88-8.26; p&lt;0.05) between ISS III and ISS II.
The ISS staging system allows an adequate stratification of patients according to overall survival in the real-practice setting. However, considering the relevance of the new cytogenetic advances, it is necessary to increase the availability and quality of iFISH in Latin America.

This study recruited 289 IBD (133 with CD and 156 with UC) patients. All were followed-up for 36 months for relapses of the disease. We defined as frequently relapsing (?1/year) patients with at least one relapse per year and as infrequently relapsing those with less than one relapse per year (&lt;1/year). We assessed the effect of the clinical predictors age, duration of disease, sex, and smoking on the frequency of relapses in IBD patients.
Sixty-four (48.1%) of the CD patients were frequently relapsing and 69 (51.9%) were infrequently relapsing. https://www.selleckchem.com/products/gdc-0032.html There was a significant association between the age and the frequency of relapse (p=0.001; OR 0.964; 95% CI 0.941-0.987, p=0.002) and between the duration of the disease and frequency of relapse (p&lt;0.001; OR 0.740, 95% CI 0.655-0.837, p&lt;0.001). Seventy-two (46.2%) of the UC patients were frequently relapsing and 84 (53.8%) were infrequently relapsing. There was a significant association between the age and the frequency of relapse (p=0.001; OR 0.964, 95% CI 0.941-0.987, p=0.002) and between the duration of the disease and frequency of relapse (p&lt;0.001; OR 0.740, 95% CI 0.655-0.837, p&lt;0.001).
We demonstrate in a relatively significant cohort of IBD patients that young age and short duration of the disease are associated with more frequent relapses.

The aim of this descriptive study of morphological research is to depict the ganglionic eminences within the embryonic and early fetal brains by using micro-MRI.
Six human embryos and fetuses ranging from 21 mm crown-rump length CRL (9 gestational week GW) to 85 mm CRL (14 GW) were examined in vitro by micro-MRI. The investigation was performed with a Bruker BioSpec 70/16USR scanner (Bruker BioSpin MRI GmbH, Ettlingen, Germany) operating at 7.04 Tesla.
We describe the morphological characteristics of the ganglionic eminences at different gestational ages. The acquisition parameters were modified for each subject in order to obtain an increased spatial resolution. The remarkable spatial resolution of 27 μm/voxel allows visualization of millimetric structures of the developing brain on high quality micro-MR images.
In our study we give the description of the ganglionic eminences within the embryonic and early fetal brains by using micro-MRI, which, to the best of our knowledge, have not been previously documented in literature. Micro-MRI provides accurate images, which are comparable with the histological slices.

Although benign, its symptoms result in economic burden and can lead to severe or even fatal complications in children, elderly and groups with comorbidities. The main purpose of the treatment is the relief of symptoms; however, the medication is often associated with adverse effects. Iota-carrageenan is a polysaccharide that reveals antiviral activity by binding to viruses, inhibiting its replications and, consequently, its viral propagation. This systematic review of the literature aims to compare the effectiveness of an iota-carrageenan nasal spray to placebo. This systematic review was conducted through research in Cochrane Database, PubMed, Science Direct, SpringerLink, Oxford Journals, Elsevier, ClinicalKey, Wiley Online Library, Embase databases, in order to collect randomized and controlled clinical trials. In total, the research provided four articles regarding clinical trials for comparing iota-carrageenan nasal spray with placebo. The results show it has potent antiviral activity compared to placebo and a favorable safety profile. Although further research is needed, the concept of a physical barrier capable of reducing viral penetration of epithelial cells in the nasal mucosa is appealing, and could lead to alternative approaches, with positive impact on global health.
